About 1.2 miles beneath Antarctica, an underground observatory is hunting for “ghost particles.” What it finds could reveal the unseen heart of a distant galaxy.
Astronomers believed in a different sequence in solar system formation with stars igniting before planets began to form. New data says no!

Webb’s NIRCam instrument recently captured this detailed image of the cloudy region around a very young protostar called L1527. Only about 100,000 years old, L1527 isn’t a star yet: it hasn’t fully pulled itself into a proper, stable sphere, and it hasn’t piled on enough mass to kickstart nuclear fusion and start pumping out its own energy. It’s more like “a small, hot, and puffy clump of gas, somewhere between 20 percent and 40 percent the mass of our Sun,” according to the European Space Agency.
But as the latest Webb photos reveal, the young protostar is making an ambitious start.
The meteorites that bombarded Mars during the early days of the inner solar system may have carried enough water to create a 300-metre-deep ocean on the planet.
Martin Bizzarro at the University of Copenhagen in Denmark and his colleagues have analysed the concentration of a rare chromium isotope, known as chromium-54, in samples of meteorites that have come to Earth from Mars to estimate how much water was deposited on the Red Planet by asteroids.
The uppermost layer of Mars contains the chemical signatures of carbonaceous, or C-type, meteorites that bombarded it as its crust solidified some 4.5 billion years ago.

All of our civilization exists only a thin layer of Earth’s surface, and our deepest mines barely scratch our planet. We often talk about finding new mineral resources on other worlds or asteroids in the future, but are we ignore a treasure beneath our feet, and what other technologies and engineering might we utilize in Earth’s depths?

During Artemis I, NASA’s Space Launch System (SLS) rocket will send the agency’s Orion spacecraft on a trek 40,000 miles beyond the Moon before returning to Earth. To capture the journey, the rocket and spacecraft are equipped with cameras that will collect valuable engineering data and share a unique perspective of humanity’s return to the Moon.
